Article Introduction：Continuous integration and continuous delivery (CI/CD) are critical in modern software development, improving code quality, reducing time to market, and reducing risk by automating code build, test, and deployment processes. This article will explore CI/CD practices in PHP and provide a step-by-step guide to setting up a CI/CD pipeline to improve code quality. How CI/CD Pipelines Work A CI/CD pipeline is a series of automated tasks for building, testing, and deploying applications whenever changes are made to the code. The pipeline typically consists of the following stages: Build: Convert source code into deployable artifacts. Testing: Evaluate the quality of your code using multiple test types such as unit tests, integration tests, and acceptance tests. Deployment: deploy artifacts to different environments, such as test loops

Article Introduction：In PHP programming, if you need to convert byte data into double-precision floating point numbers, you can use the pack and unpack functions to achieve this. In the following example, we show how to do a byte to double float conversion, along with a concrete code example. First, we need to understand the relationship between byte data and double precision floating point numbers. Double-precision floating point numbers are usually represented using 64 bits, while byte data is stored in bytes. When converting, you need to ensure that the order and format of the byte data and double-precision floating point numbers are correct. Take it

Article Introduction：Resilient Architecture The first step in building a highly available application is to establish a resilient architecture. This involves the use of redundant components such as load balancers: to distribute traffic to multiple WEB servers to avoid single points of failure. Redundant database: Provides data redundancy in the event of a failure through master-slave replication or clustering mechanisms. Distributed caching: Reduce database load and improve application responsiveness by storing data on multiple servers. Failure Detection and Automatic Failover Timely detection and response to failures is critical to high availability. PHP frameworks and tools can be used to monitor system health and automatically trigger failovers: Heartbeat monitoring: Regularly checks the status of servers and services and raises alerts when failures are detected. Automatic failover: When a failure occurs, traffic is automatically
